First let me start off with saying I am just learning PHP with smarty and am not doing this for any school/class assignment.

I am trying to create an email form that allows a user to subscribe/unsubscribe from a mailing list.

I can not figure out how to write the unsubscribe part. I used if/elseif/else:

  require_once 'include/Smarty/libs/Smarty.class.php';
  require_once 'include/';
  $smarty = new Smarty();
  define ('TEMPLATE', 'manage.html');
  $email = $_POST['email'];
  // check email against db
  if (!empty($_POST['email']))
          $query = 'SELECT id 
                      FROM subscribers 
                     WHERE email = \''.$_POST['email'].'\'';
          $res = $db->query($query);
          // do they exist? yes
          if ($res->numRows() > 0)
                  $message = 'Our records indicate that you are subscribed.';
          // unsubscribe
          elseif ($res->email == $unsub) //this is where I go wrong!!!!!
                  $query = 'DELETE FROM subscribers
                            WHERE email = \''.$_POST['email'].'\'';
                  $message = 'You have been unsubscribed';
          else {
          // they don't exist, enter new record
                  $query = 'INSERT INTO subscribers
                                    SET email = \''.$_POST['email'].'\'';
                  $message = 'Thank You!';
          'title'         => 'E-Mail Form',
          'message'       => $message

Where is this '$unsub' coming from - can't see any reference to it prior to this line.
